Flatlock Seam Frequently Asked Questions
Short answers to the questions buyers ask most often about Flatlock Seam.
What does it mean?
butted seam covered with dense stitching. Working figures for Flatlock Seam normally sit around used next to skin in mainstream production. Note flatlock machines on the tech pack so nobody tests against an older revision.
What value should be specified?
Start from used next to skin and adjust for the end use of the garment. Record elastane content alongside Flatlock Seam, because blends shift the measured value. A result outside used next to skin usually points to process drift rather than to the fibre itself.
How is it tested?
flatlock machines. Keeping reference values for Flatlock Seam lets suppliers quote without extra sampling rounds. Ask for conditioning details together with flatlock machines, since both affect the reading.
Why does it change between lots?
Process variables such as finishing temperature and elastane batch cause the normal spread of results. Working figures for Flatlock Seam normally sit around used next to skin in mainstream production. Note flatlock machines on the tech pack so nobody tests against an older revision.
Can results be compared across suppliers?
Only when the same standard revision and conditioning are used; otherwise measurements are not equivalent. Record elastane content alongside Flatlock Seam, because blends shift the measured value. A result outside used next to skin usually points to process drift rather than to the fibre itself.
